Application December 26, 1945, Serial No. 637,205

(Cl. 10S-13) 3 Claims.

The present invention relates to metal roong and is more particularly concerned with roofing metal of the corrugated type.

The primary object of the invention is to provide roofing metal of the character referred to constructed to be firmly secured to the roof rafters without the use of nails.

Another object of the invention is to provide corrugated metal roong which can be readily detached from the roof rafters for replacement or other purposes.

A further object of the invention is to provide attaching means for corrugated metal roofs of simpler and more compact construction than what is disclosed in prior devices.

With the foregoing and other objects and advantages in view the invention consists of the novel construction and arrangement of parts hereinafter described and claimed.

In the accompanying drawing illustrating the invention:

Figure 1 is a side elevation of the invention, partly in section, in operative position on the roof rafters.

Figure 2 is a vertical section on line 2--2 of Figure 1.

Figure 3 is a vertical section on line 3-3 of Figure l.

Figure 4 is a partial top plan view showing the exterior locking or lashing means for securing corrugated plates in position.

Figure 5 is a perspective view of one of the perforated locking or lashing lugs.

Figure 6 is a side elevation of one of the interior anchoring brackets to-secure the corrugated plates to the roof rafters.

Figure 7 is a partial longitudinal view showing in side elevation the interior fastening rod and anchoring bracket.

Figure 8 is a bottom plan View showing fastening rod and roof anchoring bracket in operative position.

Like numerals are employed in the drawing and following description to designate the same parts of construction. The corrugated metal roofing plates I are designed to be laid on wooden roof rafters 2 and overlap as at 3 so as to shed water from rainfalls. Each metal sheet is provided on one side and adjacent the lower edge, in operative position, with a longitudinally disposed slot 4.

In transverse alignment therewith and on the other side the sheet is provided with a perpendicular lug 5 having a perforation 6. The lug 5 is suitably positioned to t in the slot 4 of the next adjacent sheet when overlapped to form the joint.

When the sheets are laid in position to cover the roof, tie rods 1 are passed through the perforated lugs 5 and fastened in position with lock washers and nuts on the ends.

Secured to the underside of some of the plates, by welding, soldering, or other suitable means, to make them integral parts, are anchoring and supporting brackets 3 which are formed with depending longitudinally disposed tubular parts 9 for the reception of interior tie rods I0.

Tie rods I0 are preferably constructed in sections which are adjustably joined by turn-buckles II and they are passed through suitable holes I2 in the rafters. Between the ends of bracket parts 9 and the adjacent sides of the roof rafters, collars I3 are mounted on said tie rod and between same are helical springs I4 to maintain the brackets 8 in adjusted position. When the plates are positioned to be locked on the underside to the roof rafters, tie rod Il) is passed through the tubular parts of anchor brackets 8, collars and springs I3 and I3, and rafter holes I2, after which they are tightened with the turn-buckles II and fastened against longitudinal movement by end nuts and washers. No nails are necessary for emplacement of a roof constructed as aforesaid and the components may be readily taken apart for any purpose by pulling out the exterior and interior tie rods.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

1. In combination, a plurality of rooiing plates provided with projecting perforated lugs and slots positioned to engage when said plates are overlapped, a tie rod constructed to pass through said lugs and to be secured at their ends against displacement, a plate-anchoring bracket depending on the under-side of the overlapped plates and provided with a tubular part, and an adjustable tie rod constructed to pass through said tubular part and aligned holes in the roof rafters.

2. The construction'set forth in claim 1 and a 2,419,663 ,i f 3 4 'resilient element to maintain said anchoring REFERENCES CITED bracket in adjusted relation to said rafters. The following references are of record m the 3. A roofing plate comprising a corrugated me of this patent:
